Sonorium creates immersive music listening sessions held in unique locations such as the Grand Palais, the Musée du Louvre or the Parc Floral, experienced on high-end hi-fi sound systems. Each session is presented by a music critic who introduces the featured album and conducts a live interview with the artist, thus bringing listeners and musicians together.

The visual identity is built around a series of simple line motifs that are reminiscent of sound frequencies. These motifs are designed using a grid of seven lines relating to the seven notes of the musical scale. A custom logotype and bold typographic treatment complement the dynamic graphic system.
